UNITED STATES PATENT OFFICE.

METAL PRESSING AND SHAPING- TOOL.

Application filed. April 15, 1924. Serial No. 706,787.

To all whom it may concern:

Be it known that I, JOHN R. MlIOHAEL, a citizen of the .United States, residing at Arab, in the county of Marshall and State of Alabama, have invented certain new and useful Improvements in Metal Pressing and Shaping Tools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention provides a tool specially adaptedfor' the use of a smith in the reshaping of plow and cultivator sweeps and which is adjustable to insure proper setting of the eye and wings of the sweep whereby it will operate properly to shed the soil and trash and operate with a minimum resistance .so as not to unnecessarily add to the draft when plowing or cultivating.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet dilferent conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention.

Referring to the accompanying drawings forming a part of the application:

Figure 1 is a side view of a metal pressing and shaping tool embodying the invention, partly in section,

Figure 2 is a front view thereof, Figure 3 is a horizontal sectional view on the line 33 of Figure 1,

Figure 4 is a horizontal sectional view on the line 4.-4 of Figure 1,

Figure 5 is a detail sectional view on the line 55 of Figure 3,

Figure 6 is a detail sectional view on the line 66 of Figure 3,

Figure 7 is a detail view of an adjusting pin and a portion of the anvil, the latter being shown in section,

Figure 8 is a view of an adjusting pin as seen from the lower end, and

Figure 9 is a detail view of the adjusting wedge.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

I The tool comprises a base 1 provided with depending lugs '2 which are apertured to receive bolts for securing the tool to a post or other suitable support. A base 3 is adapted to be bolted or otherwise secured to the base 1 and a post 4 rises from an end portion thereof and terminates at its upper end in an overhanging portion 5. A bed 6 projects forwardly from the foot of the post 4- and may form a part of the ase 3 or be bolted thereto and to the base 1 as found most advantageous. An anvil is mounted upon the bed 6 and comprises a body portion and a middle and side platens which are relatively adjustable to admit of giving the required shape to the sweep. The anvil as a whole has the general outline of a plow sweep and comprises a middle and side portions. The middle and side portions of the body of the anvil are designated by the numerals 7 and 8, respectively, and are fixed.

Hooked members 11 are mounted upon the outer ends of the side portions 8 of the body of the anvil and are adjustable by means of set screws 13. Hooked members 12 are mounted upon the parts 8 of the anvil intermediate the ends thereof and are adjustable by means of set screws 14 and these hooked members and set screws provide for adjustment of the side wings of the sweep when setting the tool to give the required shape to the sweep to be forged. The middle platen 9 is adjustable by means of a wedge 15 which is adapted to be set by means of an adjusting screw 16. A pivot pin 17 connects the middle platen 9 to the middle portion 7 of the anvil body and a screw 18 coacts with a slotted post 19 to hold the platen 9 in the required adjusted position. A pin 20 projects upwardly from the platen 9 to enter the eye of the sweep and maintain the shape thereof during the pressing or forging operation.

A plunger 21 cooperates with the anvil and conforms approximately to the shape thereof. A link 22 is pivoted at its lower end to a stud of the plunger and is provided at its upper end with a strap 23 which is fitted to an eccentric 24 which is adjustable to vary the effective leverage for operating the plunger. An operating lever has the eccentric 24. connected thereto and is pivoted to the overhanging portion 5 of the post 4. This operating lever comprises a 7 at different distances from the longitudinal axis of the pins, and by setting the pins provision is had for adaptin the anvil to sweeps having wings of different widths. When the sweeps have wide wings, the adjusting pins 29 may be removed.

Preliminary to shaping a sweep, the platen 9 of the anvil is adjusted so as to give the proper set to the eye and wings of the sweep and the latter is heated in a forge and placed upon the anvil and the lever operated to lower the plunger, thereby causing the sweep to conform to the anvil, as will be readily understood. Links 31 connect the link 22 to the post 4:, thereby causing the plunger to coact properly with the anvil during the pressing operation. A bail 32 connected to the links 31 engages V a rearward extension 33 on the plunger when it is in its lowermost position and assists in raising the plunger from the sweep after the latter has been pressed.

What is claimed is: 1. A tool of the character specified for shaping plow and cultivator sweeps, the

. same comprising an anvil including adjustable middle and side portions, and a plunger in cooperativerelation with the anvil.

2. A tool of the character specified for shaping plow and cultivator sweeps, the same comprising an anvil including a body and platens, the latter being adjustable relatively to the body, and a plunger in cooperative relation with the anvil.

3. A tool for shaping plow and cultivator sweeps, the same comprising an anvil including a middle and side portions, and

means for independently adjusting the respective members, and a plunger in cooperative relation with the anvil.

4. A tool of the character specified comprising an anvil including a body portion and a middle and side platens, means for independently adjusting the several platens, and a plunger in cooperative relation with the anvil.

5. In a tool of the character set forth, an anvil comprising a middle and side body portions and a middle and side platens, and independent adjusting means mounted upon the respective parts of the body and adapted to effect adjustment of the several platens.

6. In a tool for shaping plow and cultivator sweeps, an anvil comprising a body portion adapted. to support the eye and wing of a sweep, platens mounted u on the respective portions of the body, an means for independently adjusting the respective platens and securing the same in the required adjusted position.

7. A tool for shaping plow and cultivator sweeps, the same comprising an anvil body including a middle and side portions, platens mounted upon the respective parts of the body, and means mounted upon the body portion of the anvil and adapted to effect independent adjustment of the respective platens.

8. In a tool for shaping plow and cultivator sweeps, and in combination with an anvil adapted to receive the sweeps, adjusting pins mounted upon the anvil and comprising faces disposed at different distances from the center of the pin and adjustable to admit of the required stop face being brought into operative position.

9. In a tool of the character specified, an anvil, a post at one side of the anvil, a plunger adapted to coact with the anvil, an operating lever mounted upon the post, an eccentric link connection between the operating lever and plunger, a link connection between the post and plunger carrying link, and a bail carried by said link connection and adapted to coact with the plunger.

10. In a tool of the character specified, an anvil, a post at one side of the anvil, a plunger, an operating lever, an eccentric having adjustable connection with the operating lever and post whereby to vary the effective leverage of the operating lever, and a link connection between said eccentric and plunger.

11. In a tool of the character specified, a plunger, an operating lever therefor, an eccentric having adjustable connection with the operating lever and with a support whereby to vary the effective leverage of the operating lever, and a link connection between said eccentric and plunger.

12. A tool of the character specified comprising a base adapted to be secured. to a suitable support, a post provided at its lower end with a base adapted to be secured to the supporting base and having an extension forming a bed, said post terminating at its upper end in an overhanging portion, an anvil body mounted upon said bed, a middle and side platens mounted upon corresponding portions of the anvil body,
